The use of Smartview will make the lesson flow, as the students explore the various graphs of the parabola (quadratic equation).

## Given a graph...what is the function?

#### Activity Overview

Understanding how to associate a function of a parabola with its graph. Students will explore varies functions and determine its graph. They will then use what they learned to predicate where a particular graph of a different function will appear on the coordinate plane.

#### Before the Activity

The students will have already seen the graph of a parabola is y = x2. They should also record the other graphs they explore to conclude a pattern that they should notice.

#### During the Activity

Print copy of the attached document for each student.

#### After the Activity

Review student results and discuss questions that appeared to be more challenging. Re-teach concepts as necessary.
